dsda: put non-sync settings to ini but not pass them on init

if we set them on core init that's how it'd remember them in the reference state, so loading states made with different init options would fail to load

instead we set everything to default on init and then change to what the user set during the first frame advance. that way reference state remains the same so states using different options keep working across all variants

need to not show core messages tho when something is changed from default, because now they appear on init and state load rather than only on explicit change
